Panel lock for a float mount connector

An electrical connector housing (100) is mounted to float in a back panel (P2) of a drawer. The panel has a T-shaped cut out (178). The housing (100) has upper flanges (144) lower flanges (146) and a top flange (150). In order to mount the connector hosing (100) to the panel, the upper flanges (144) are inserted through the transverse part (182) of the cut out (178) and the housing (100) is then moved along the perpendicular part (180) of the cut out, so that the upper flanges (144) engage the front face of the panel (P2) and the lower flanges (146) engage the rear face of the panel (P2), to retain the connector in the cut out (178). The top flange (150) has one or more sockets (152) and in the, or each, socket (152) a panel lock member (162) having a pnael lock (176). The, or each, panel back member (162) is latched in a retracted position in the socket (152). The, or each, panel lock member (162) can be advanced by pressing it forwardly whereby the panel lock (176) projects forwardly of the top flange (150) thereby preventing the housing (100) returning to such an extent that the upper flanges (144) are aligned to such an extent that the upper flanges (144) are aligned with the transverse part (182) of the cut out so that the housing (100) can fall from the panel (P2).
